On a rocky hillside in Fort Collins, Colo., is a “mega den” of hundreds of rattlesnakes.

They live between the rocks year-round, but in the summer, the only snakes to remain in the area are preparing to give birth.

“So this is not quite what we might expect, like a black bear den or a grizzly bear den or something,” says Scott Boback, professor of biology at Dickinson College and co-leader of Project RattleCam.

“This is more like a rock face, where there’s a number of holes that go underground — crevices and cracks in between the rock — and you will see snakes go in and out of these holes. We don’t quite understand exactly what’s going on beneath the surface.”

Project RattleCam, a research project based in California, is making it possible for people to observe the snakes with a live webcam. Cameras tucked away in the hillside livestream the snakes to their website.

Boback says this is an especially interesting time to watch the snakes because of their behavior during pregnancy.

Unlike other snakes, rattlesnakes give birth to live babies — or “pups” — and care for their young for a few weeks after birth. Typically, snakes live solitary lifestyles, but when they’re pregnant they coalesce around nurseries called “rookeries.”

“So when they are aggregated together, as scientists, you got to ask the question about why, what’s going on,” Boback says. “And so that’s one of the things that we’re doing with the camera, is we are interested in how these animals may be interacting with one another. Like, do they tolerate each other?”

Project RattleCam permits Boback and his colleagues to observe the snakes without disruption. It also allows the public to participate.

“We’re sort of right next to the general public who are helping us in that way by making certain observations,” he says. “They’re identifying individual snakes. They can go back and they can rewind the video and they can stop at certain frames, identify unique features on an individual and name the snake. And that allows us to sort of move forward in tracking individuals.”

Researchers from Project RattleCam understand some of the species’ strange behaviors, like rain harvesting, where the snakes coil up like a teacup and collect water in their body.

Other data is still being studied, but focuses towards the interactions of the mothers during their gestation period.

“If you have a whole bunch of expectant mothers together, they don’t all give birth exactly at the same time,” Boback says. “Essentially, what you have is the opportunity for other mothers to babysit for the mother that actually has given birth to those pups.”

Boback says that observing these traits helps correct wrongful assumptions about the species.

In a study published by the journal Biology of the Rattlesnakes, Cale Morris, a researcher and educator at the Phoenix Herpetological Sanctuary, used a fake leg to mimic stepping on 175 rattlesnakes. In the entire study, only six snakes struck back at the prop.

In May, NPR visited the rattlesnake training course taught by Morris in Scottsdale, Ariz. He told the class: “I just want you to look at this for what it is. This is not an aggressive animal. I see a shy, scared animal.”

Boback says there are many more mysteries to the social behavior of rattlesnakes, and RattleCam is adding insight to a neglected portion of zoology.

“The way that we have always measured sociality is often with primates,” he says. “Things like us, where we smile and we frown and we look at each other and have these very specific facial expressions.”

“Because a snake doesn’t do that, we maybe assumed that there is no socialization going on when, in fact, the snakes are getting a sense of smell from each other every time they stick their tongue out. And so there are chemicals in their skin that we believe they’re using to understand each other. Who is who? They have a way, perhaps, of detecting each individual. Is this my sister? Is this my aunt?”

Small plane pilot injured in northwest Colorado crash after suspected engine failure


The pilot of a small plane that crashed Sunday in Eagle County walked away with minor injuries, according to the sheriff’s office.

Investigators believe the plane’s engine failed midflight, causing it to clip a tree and crash near Dotsero, in the 1200 block of Sweetwater Road, according to a news release from the Eagle County Sheriff’s Office.

Dotsero is roughly 18 miles northeast of Glenwood Springs and 43 miles west of Vail.

Vail Public Safety Communications was notified about the incident by a Garmin alert shortly after 2 p.m. Sunday, the release stated. Shortly after, someone called to report the plane crash.

Eagle County deputies responded to the crash site and found a 48-year-old man with a minor cut. He was the plane’s pilot, sheriff’s officials said.

The nearby plane had crashed onto its nose with its tail in the air, photos from the sheriff’s office show.

Bennett Zmolek’s first goal in four years sparks UND past Colorado College

Bennett Zmolek’s first goal in four years sparks UND past Colorado College


COLORADO SPRINGS, Colo. — There was no elaborate celebration from Bennett Zmolek.

In fact, he didn’t even see it go in.

“I saw Resch coming at me,” Zmolek said of teammate Cole Reschny. “I was like, I guess it went in.”

Zmolek scored his first goal in nearly four years to help UND beat Colorado College 5-2 on Saturday night in Ed Robson Arena.

His last goal was Jan. 20, 2022, when he was a freshman at Minnesota State against St. Thomas. That was 1,450 days and three hip surgeries ago.

With the game tied 1-1 in the second period, Zmolek spotted open ice on the right side of the rink and pinched from his defensive spot. Reschny made a cross-ice pass and Zmolek one-timed it five-hole on Tiger goalie Kaidan Mbereko.

“I’d say huge props to Resch,” Zmolek said. “He set it all up. I just had to tap it in.”

Teammate Dylan James grabbed the puck for Zmolek to keep.

“So proud of him,” James said. “Obviously, he’s been through a lot these past couple years. He’s played minimal games the last two years and he was voted captain. That shows what kind of guy he is. He’s the rock of our team. It’s very special seeing him get his first in a UND jersey.”

Zmolek’s teammates celebrated the goal more than he did.

“We were all screaming on the bench,” forward Anthony Menghini said. “He’s such a great leader, such a great captain, does all the right things. For him to put it in the net was huge.”

UND also received goals from James, Tyler Young, Abram Wiebe and Reschny. James and Reschny tallied assists and had two-point nights, while Menghini notched two assists.

UND (17-5) took four points from the weekend after losing Friday’s series opener 3-2 in overtime.

The Fighting Hawks finally got to Tiger goalie Kaidan Mbereko, who had won six in a row against UND. Mbereko gave up four goals on 24 shots before leaving with an apparent injury in the third period.

“I don’t believe our record is great against CC, but this team is different,” James said. “It feels great to bounce back from yesterday and get a win.”

The Fighting Hawks sit atop the National Collegiate Hockey Conference standings, five points ahead of Denver. The Pioneers come to Ralph Engelstad Arena next weekend.

“Their coach. . . I have a lot of respect for Kris Mayotte,” UND coach Dane Jackson said. “He kind of mentioned that he really thought our North Dakota mentality was evident this weekend. That was pretty nice for him to say.”

Jan Špunar, starting on consecutive nights for the first time since Dec. 5-6 at St. Cloud State, stopped 19 of 21. He allowed a pair of goals to defenseman Mats Lindgren, a midseason pickup from the ECHL.

But the night belonged to Zmolek.

After the game, Zmolek was asked what he remembered about his last goal.

“St. Thomas, right?” he said. “Their old barn. Low blocker.”

That goal came at the end of the 2021-22 season. Zmolek missed nearly the entire 2022-23 season due to hip surgery.

He transferred to UND in the summer of 2023, and helped anchor UND’s defensive corps to a Penrose Cup in 2023-24. He missed all but one game last year with another hip surgery.

“I’m so happy for him,” Jackson said. “It was a great read, a great pass and he got a lot of wood on it. It was really a high-skill play. The guys are so happy for him. He’s such a leader for us in so many ways. Obviously, most of the time it’s with his defensive play and penalty killing and everything else. But to see him bring out the offense in a big moment, I was just so happy for him. He’s a warrior.”

Notes: UND wore its black jerseys. It is 4-1 in the black jerseys this season. Colorado College wore gold. . . UND played without Josh Zakreski (lower body) and Cody Croal (illness). The Fighting Hawks moved Jayden Jubenvill into the lineup for Sam Laurila. . . Colorado College played without forward Owen Beckner (upper), forward Brandon Lisowsky (lower), defenseman Max Burkholder (lower) and defenseman Colton Roberts (upper).
